the refrigerant. Next the refrigerant flows through the condenser, where it condenses from vapor form to liquid form, giving off heat in the process. The heat given off is what makes the condenser "hot to the touch." After the condenser, the refrigerant goes through the expansion valve, where it experiences a pressure drop. Finally, the Download scientific diagram | Schematic diagram of variable refrigerant flow air conditioning system from publication: Comparison study of a novel solid desiccant heat pump system with EnergyPlus ... • Normally a different refrigerant would be used in each separate cycle, in order to match the desired ranges of T & P. • The Ts diagram shows an ideal double-cascade system using the same refrigerant in each loop. • If two different refrigerants => two separate Ts diagrams must be used. • Note: Normally , they are ﬁxed by Counterﬂow Variable Refrigerant Flow (VRF) heating and cooling systems promise energy efficiency, flexibility and improved comfort in small to mid-sized commercial buildings. Traditional heat pumps have been evolving in Asia over the last thirty years, and VRF systems are now the preferred HVAC system for small and medium commercial buildings in both Asia and

The refrigerant then flows back to the compressor via the reversing valve and the cycle repeats itself. Q: How does the refrigerant flow through the system in the cooling mode? A: The refrigerant (upon leaving the compressor via the red line in the following diagram) first flows through the reversing valve where it is directed to the outdoor coil.
